Product Overview
The 5SE Series is an ultra‑miniature waterproof slide switch engineered to meet the dual challenges of high‑density integration and humid environments, with the design philosophy of "compact size, all‑scenario protection." Within a precision signal‑level power rating of just 0.4VA, the series offers complete coverage of both SPDT and DPDT circuit topologies, and is innovatively equipped with a transparent waterproof cover that elevates the protection rating to IP65 – effectively guarding against dust ingress and low‑pressure water jetting. Its ultra‑compact footprint makes it an ideal choice for space‑constrained equipment – from precision test instruments and outdoor communication devices, to professional microphones and household water heaters. The 5SE Series delivers exceptional design freedom with minimal PCB real estate, enabling engineers to achieve reliable circuit switching within the tightest of spaces.
Technical Parameters
Key Features
1. Ultra‑Miniature Package – A Lifesaver for High‑Density PCBs
Ranking among the most compact in the slide switch category, the 5SE series is purpose‑built for the ever‑shrinking internal spaces of modern electronic devices. Whether in multi‑layer stacked communication modules or space‑constrained portable test equipment, the 5SE series delivers reliable circuit switching with minimal footprint, freeing up valuable board space for other critical components.
2. IP67 Waterproof Cover – Reliable in Humid Environments
Equipped with a standard transparent waterproof cover that precisely mates with the switch body to achieve IP65 protection. The transparent material does not obstruct visual identification of the switch position, while effectively blocking water mist, splashes, and dust ingress. For moisture‑prone applications such as water heaters, outdoor communication cabinets, and laboratory humid environments, this design significantly enhances long‑term equipment reliability.
3. 0.4VA Precision Signal‑Level – Dedicated to Low‑Power Circuits
Optimized for low‑voltage, low‑current precision signal circuits, with a maximum rating of 0.4VA @ 48V AC/DC – perfectly matched for sensor signal switching, logic‑level control, communication protocol selection, and similar applications. Gold‑plated contacts ensure stable conduction at micro‑ampere currents, completely eliminating signal attenuation caused by contact oxidation in "dry circuit" applications.
4. Three Terminal Options – Adapting to All PCB Layouts
Offering three terminal styles to cover the full range of manufacturing scenarios – from hand soldering to automated production:
PC Pin Terminal: Standard through‑hole type, compatible with wave soldering and manual soldering
Side‑Actuated Terminal (MZ Type): Laterally routed, ideal for horizontal trace routing inside ultra‑thin devices
SMT Terminal: Supports reflow soldering for automated production, improving assembly efficiency and solder joint consistency
5. Military‑Grade Contact Process – Ensuring Signal Purity
Contacts are made of phosphor bronze substrate, plated with a nickel barrier layer followed by a gold overlay. The nickel layer effectively prevents copper ion migration to the gold surface, while the gold layer provides extremely low contact resistance and excellent chemical stability. This dual protection ensures that the contacts maintain a consistently low resistance of ≤50mΩ even under high‑frequency switching.
